What symptom is typically associated with Major Depressive Disorder?

Anhedonia is a hallmark symptom of Major Depressive Disorder (MDD). It refers to the diminished ability to experience pleasure or interest in activities that are usually found enjoyable. This can include social interactions, hobbies, and other daily activities. The presence of anhedonia often significantly impacts a person's quality of life and functioning, making it a critical criteria for diagnosing MDD according to the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition).

In the context of MDD, anhedonia reflects the disorder's effect on a person's emotional state and overall motivation. Individuals may find themselves feeling numb or disconnected from experiences that previously brought them joy, which is a key aspect of the depressive experience.

Other options like hallucinations, hyperactivity, and mania are not typically associated with MDD. While hallucinations can occur in some severe cases or comorbid conditions, they are not a defining feature of MDD. Hyperactivity is more associated with conditions such as ADHD or certain mood disorders where there is an elevated mood. Mania is characteristic of Bipolar Disorder rather than Major Depressive Disorder, distinguishing it from the unipolar nature of depression.
